perienced with grasshopper, but so far I've managed to combine the following:
Giulio Piacentino's "Catenary arch from height" script
Pirouz Nourian's "Mobius" script (Obtained from a friend)
End Result:
Here's where I'm stuck: I want the mobius twist to revolve around the midpoint of the arch, but the script uses the input values to determine the endpoints, resulting in a weird sinuous shape when viewed from above. Also, the secondary end points (generated by the mobius script, determining the width of the surface) are generated by default along the z axis, resulting in an arch that only touches the "ground" at two points. I attempted to work around this issue by trying to force the zHeight parameter to correspond with the y axis (thus rotating the arch 90 degrees so it would lay "flat"), but the script interprets the third point as a value and not as an actual point to bisect. I thought this might be an issue with the C# component that I obtained from Giulio Piacentino's script, so I attempted to tinker around with the source code. Unfortunately, I'm not fluent in C# so I only managed to mess everything up (I've since recovered the code from the cache). Anybody got some ideas? -BC …

, Engineer and Researcher from France with broad programming experience. He is the author of the City in 3D Rhinoceros plugin for creation of buildings according to geojson file and with real elevation. Guillaume already created a new component: "Address to Location". It enables getting latitude and longitude values for the given address:
2) Support of Bathymetry data: automatic creation of underwater (sea/river/lake floor) terrain. This feature is now available through new source_ input of the "Terrain generator" component. Here is an example of terrain of the Loihi underwater volcano, of the coast of Hawaii:
3) A new terrain source has been added: ALOS World 3D 30m. ALOS is a Japanese global terrain data. Gismo "Terrain Generator" component has been using SRTM 30m terrain data, which hasn't been global and was limited to -56 to +60 latitude range. With this addition, it is possible to switch between SRTM and ALOS World 3D 30m models with the use of source_ input.
4) 9 new components have been added:
"Address To Location" - finds latitude and longitude coordinates for the given address.
"XY To Location" - finds latitude and longitude coordinates for the given Rhino XY coordinates. "Location To XY" - vice versa from the previous component: finds Rhino XY coordinates for the given latitude longitude coordinates. "Z To Elevation" - finds elevation for particular Rhino point. "Rhino text to number" - convert numeric text from Rhino to grasshopper number. "Rhino unit to meters" - convert Rhino units to meters. "Deconstruct location" - deconstructs .epw location. "New Component Example" - this component explains how to make a new Gismo component, in case you are interested to make one. We welcome new developers, even if you contribute a single component to Gismo! "Support Gismo" - gives some suggestions on how to make Gismo better, how to improve it and support it.
5) Ladybug "Terrain Generator" component now supports all units, not only Meters. So any Gismo example file which uses this component, can now use Rhino units other than Meters as well. Thank you Antonello Di Nunzio for making this happen!!
Basically just forget about this yellow panel:
This panel is not valid anymore, so just use any unit you want.
6) A number of bugs have been fixed, reported in topics for the last couple of weeks. We would like to thank members in the community who invested their time in testing, finding these bugs and reporting them: Rafat Ahmed, Peter Zatko, Mathieu Venot, Abraham Yezioro, Rafael Alonso. Thank you guys!!! Apologies if we forgot to mention someone.
The version 0.0.2 can be downloaded from here:

azione parametrica e generativa attraverso Grasshopper, plug-in di programmazione visuale per Rhinoceros 3D (uno dei più diffusi modellatori NURBS per l‘architettura e il design). Il workshop mira a gestire e sviluppare il rapporto tra informazione e geometria lavorando sui sistemi ad involucro in condizioni specifiche.La discretizzazione di superfici (pannellizazione Nurbs o Mesh), la modellazione delle geometrie attraverso informazioni (siano esse provenienti da analisi ambientali, mappe o database) e l’estrazione e la gestione di queste informazioni, richiede la comprensione di strutture di dati al fine di gestire completamente processo che va dalla progettazione alla costruzione.I partecipanti impareranno come costruire e sviluppare strutture di dati parametrici per informare geometrie ‘data-driven’ e come estrarre le informazioni rilevanti da tali modelli per il processo di costruzione.
Modulo 2 – Il workshop, volto a promuovere le nuove tecnologie digitali di supporto alla progettazione e alla fabbricazione, esplorerà l’integrazione tra design e prototipazione tramite processi di stampa 3d di materiale ceramico al fine di comprenderne allo stesso tempo sia il comportamento del materiale che i vincoli e le opportunità offerte dall’utilizzo di tali tecnologie.Infatti utilizzando grasshopper ed una macchina a controllo numerico i partecipanti apprenderanno le modalità per la generazione parametrica dei modelli e la creazione del codice per la loro prototipazione (Gcode creato direttamente in Grasshopper). Il workshop darà quindi ai partecipanti la possibilità di testare direttamente i loro elaborati digitali stampandoli in modo da comprendere come le informazioni articolate tramite tali strumenti di design producano specifici effetti sia morfologici che estetici.…

I've found getting really good handling of static vs kinetic friction to be a pain though.
Distinguishing between collisions and resting contact generally becomes more complicated than it might first appear.
If the collision with the mesh or ground is 'hard' I project the particle positions, so they can never penetrate, and reverse the component of their velocity normal to the surface (multiplied by the restitution factor). This means that whenever you have some structure of springs resting on a hard surface, there is usually still some tiny imperceptible bouncing. This makes it hard to properly apply static friction (which would zero the tangential velocity if the tangential force was below some threshold and it is not already sliding), because particles are generally not perfectly on the surface, even when apparently at rest. Obviously it's not good to have friction affecting things that aren't touching the surface.
This is the origin of the 'settle' parameter in the settings. The idea was that when the motion of a particle normal to the surface drops below that limit, it will be totally zeroed, and the particle becomes properly resting on the surface. I never really like having to use these kind of weird ad hoc fixes though.
Alternatively, if the collision is 'soft' I use a spring-like force to push particles out of the ground/mesh.
This can cause problems because in many cases you just want a simple constraint that they never go below ground level, and there is a limit to how stiff you can make these spring-like forces.
The advantage though, is that because any particle resting 'on' the ground/surface will actually be slightly below/inside it, and one can use this to decide whether to apply contact friction.
With bouncing collisions, it is a little simpler. There is just the question of what to do with the velocity component tangential to the surface. See the bottom comment by me here, for more on the 'tumble' setting:
http://www.grasshopper3d.com/video/kangaroo-traction-test
So you see, it is challenging to get one consistent model that will give correct behaviour for all cases (eg a simple static 'leaning ladder' type problem, a bouncing particle, and vehicle wheel traction), without having several of these odd seeming and non-intuitive settings.

m is different from email spam.
Email spammers want you to buy their product. You are the target of the ad contained in each email spam you receive. Comment/web spammers want your readers to buy their product. You (the blogger, author, moderator) are not the target.
2. Web spammers are social engineers.
Email spammers write messages to get your attention. Comment spammers write messages to escape your attention. They want you to believe they are real bloggers, real people, writing real comments, so you’ll approve the comment and publish it on your site. They use flattery, appeal to your good nature, and simply lie in order to convince you to give them the benefit of the doubt.
3. Web spammers are basically advertising on your blog..
..and they're keeping all of the profits. They’re not even asking your permission first. Right now someone is offering to sell links from your blog to anyone willing to pay a few dollars (or a few cents). If your blog is well known, it may even be listed by name, with backlinks for sale at a set price.
4. It’s all about the backlinks.
Web spammers are selling links from your blog to their clients. They do this to game the search engines and trick your readers into visiting dubious web sites. Their clients are sometimes seemingly harmless, but are often peddling fake pills, porn, scams and malware. Sometimes they’ll use “buffer sites” – that is, innocent looking web pages intended to disguise the fact that they’re really advertising something more sinister.
5. Spammers employ humans.
Not all spam is delivered by spambots. Spammers are increasingly using humans to write and post comments by hand. Typically they are exploiting low-paid workers in internet cafes, schools and factories. Sometimes they are viral marketers paid to promote a new product. Either way they are trying to exploit your blog for their profit – and hoping to do it without you noticing.
